Currently, several approaches offer enhancements for sensory, motor and cognitive brain functions, _____(II)_____ for mood and emotions. Such enhancements may be achieved pharmacologically, using brain implants for recordings, stimulation and drug delivery, _____(III)_____ employing brain-machine interfaces, or even by ablation of certain brain areas. In this Research Topic, we welcome papers critically evaluating the existing methods of brain augmentation, introducing new approaches and probing particular parts of brain circuitry and particular neuronal mechanisms as candidates for an enhancement. We welcome scientists from different fields: from neuroscience of microcircuits to systems neuroscience of large-scale networks and neural engineering. The work can be experimental or computational. Reviews and papers on philosophical and ethical issues are _____(IV)_____ welcome. While the scope of possible relevant topics is broad, the authors are encouraged to clearly indicate how their studies address the announced theme of brain augmentation. Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements.
